NOTES
All DATA have been obtained by the data authors for the following conditions:
water - distilled deionized water
temperature - 25 degC
method - reflectance (near-normal and at 53 deg) measurement (relative to that of an aluminum mirror) performed by the data authors) and transmission data of Plyler EK and Griff 1965 in the 4000-1400 cm^-1 range, Plyler EK and Acquista 1954 in the 1400-1000 cm^-1 range, Draegert DA el al. 1966 in the 1200-300-cm^-l range. The transmission data were modified where necessary to assure consistency with m' and m" values. 
The absorption coefficient, a, (the CALC column) has been calculated by M. Jonasz (a = 4 PI m" / wavelength)
